Materials Data on Hf2Pt3 by Materials Project
Hf2Pt3 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Hf is bonded in a 9-coordinate geometry to nine Pt atoms. There are a spread of Hf–Pt bond distances ranging from 2.76–2.96 Å. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a distorted body-centered cubic geometry to eight equivalent Hf atoms. In the second Pt site, Pt is bonded in a 10-coordinate geometry to five equivalent Hf atoms.
